  • – To navigate to a particular URL.
  • navigate.back() – To navigate back to a URL in browsing history.

Ques 6: What are different Identifiers used in Selenium WebDriver?

There are 8 Locator’s or Identifiers in Selenium WebDriver:

  • “/” is used to access the immediate child of a tag whereas “//” is used access any child of a Tag.
  • “/” is used in absolute xpath and “//” is used in writing relative xpath.

For Example:

html/body/table/tbody/tr[2]/td/input – This is an example of absolute xpath. we are navigating to input tag by accessing immediate childs.

Actions action = new Actions(driver);


Ques 13: What is the significance of contextClick() method in Selenium?

  • contextClick() method is used to perform right click event of Mouse Operation.
  • Actions class from Selenium WebDriver has this  method “contextClick()” which performs Right Click.

Ques 17: How to handle a dropdown in Selenium WebDriver?

  • Select class from Selenium WebDriver is used to handle Dropdown.
Select dropdown = new Select(Element);

Now this dropdown object of class Select has below methods to work with on a Dropdown:

  • selectByValue(“value”); – Selects an option by value from a dropdown.
  • selectByVisibleText(“text”); – Selects an option by visible text from a dropdown.
  • selectByIndex(index); – Selects by index from the dropdown.
  • deselectByValue(“value”); – Deselects an option by value from a dropdown.
  • deselectByVisibleText(“text”); – Deselects an option by visible text from a dropdown.
  • deselectByIndex(index); – Deselects an option by index from a dropdown.
  • deselectAll(); – Deselects All options in a dropdown.
  • isMultiple(); – Boolean operation which verifies whether a dropdown allows multiple selection or not.
  • getOptions(); – Returns a list of all options from a dropdown.
  • getFirstSelectedOption(); – Returns first option selected in a dropdown as a WebElement .
  • getAllSelectedOptions(); – Returns a list of all selected options in a dropdown.

Ques 18: How to perform Drag and Drop operation using Selenium WebDriver?

  • Drag and drop operation means to grab an object and move it to some other location. Selenium WebDriver provides Actions class to perform drag and drop operation.
Actions action = new Actions(driver);

  • getWindowHandles() – method returns a set of unique sessionIds of all the opened windows.

Ques 22: How to switch to a new window (or a new tab) which opens up after you click on a link?

  • When a click operation on link results in opening up of a new window (or new tab), the control of selenium does not automatically switches to the new window (or new tab). We have to write code to switch selenium code to the new window.


  1. Save the sessionId or window handle of Parent window.
  2. Click on the click which performs opening up of a new window operation.
  3. Get the sessionId of Child Window.
  4. Switch to the child window.
// Defining variables to store session id of parent window and child window
String sParentWindow, sChildWindow;

// Getting session id of parent window
sParentWindow = Driver.getWindowHandle();
System.out.println("Session Id od Parent window "+ sParentWindow);

//Clicking on a button or link which results in opening up of a new window

//Getting session Id of child window
sChildWindow = Driver.getWindowHandles().toArray()[1].toString();
System.out.println("Session id of Child Window "+ sChildWindow);

//Switching to Child Window
System.out.println("Title of Child Window is : "+ Driver.getTitle());

//Switching back to parent window
 Ques 23: What is the name of the headless/GUI-less browser?
  • HTML UnitDriver, PhantomJS are two famous headless browsers. Now, even chrome has provided a support of headless browser testing.

Ques 24: How to switch back from a frame?

  • defaultContent() – is the method to switch back from a frame to the parent window.

Ques 25: Write a code to get URL attribute from a link webElement?

  • Links are represented by anchor tag on a web page  “<a>”
  • Anchor tag has an attribute called href which keeps the value of the URL (address where will navigate to after clicking).
  • getAttribute() – method is used to get the attribute from a WebElement.
WebElement link = Driver.findElement(By.linkText("Advertise"));
String url = oLink.getAttribute("href");
System.out.println("From attribute :"+ url);
Soon we will come up with next series of Selenium Questions.
